. Application filed m a1, 1919, Serial 1110. 314,4 7.

To all whomitmay concern: Be it known that I, Emma cltizen of the United States, residing at Williamsport, in the son ty of Lycoming and State of Pennsylvania 'have'mvented' certain new anduseful Improvements in Machines for Finishing Flooring, of which a the following is a specification, reference being had therein to the accompanying drawing. L

,This invention relates to certainnew and useful improvements in machines for finishmg flooring, and il a ompanion application of my applications Serial Numbers 314,464;

314,465 and 314,466 filed even date herewith, the object being to provide a machine with means for finishin and coating previously varnished strips 0 flooring-with a coating of wax on the varnished surface and a coating of oil on the opposite face, whereby the entire surface of the strip will be given a coating. f

A still further object of the invention is to provide a construction of machine which 7,

is substantially the same asshown in my companion applications with the exception that the parts are re-arranged and additlonal elelments are added to obtain the desired resu t.

A still further object ofthe invention is to provide a machine havin a pair of receptacles provided with disc arge openings between which a strip of flooring is adapted to pass so as to receive a coating of wax on one surface and a coating of oil on the'op- .posite surface.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

frame 1 having a driving mechanism constructed identically as shown in my companion applications, and provided with. a guidewa y 2 for supporting and guiding the strip of floorin on edge in Its passage The strip is moved through-the guidewa by feed rollers 3 constructed and operate in identically the same manner as shown in my companion application, Serial No. 314,464, whereby the feed rollers are under the control of, the operator through the medium of a hand lever 4 whereby they can be thrown into and out of contact with the opposite faces of the strip so as to start and stop the movement of the strip. The feed. rollers, are held in frictional contact with the opposite faces of the strip through the medium of the weighted arms, crank and lever, the construction of applications filed even date herewith.

Arranged in advance of the feed rollers are a series of rollers5 adapted to engage the finished face of the flooring strip as it passes through the guideway. These rollers are carried b a suitable sup ort 6, con structed as s own in Serial 0. 314,466, which support is secured to the guidfirway by bolts 7 on the opposite ends of which is glass burnishers 9' held in frictional contact with the varnished face of the strips by rubberblocks 10 and wedges 11, the details of construction of which are clearly shown in Fig. 2, and as the strip passes the burnishers 9, which are arranged obliquely 1n respect to the path of travel of the strip of flooring, the varnished face of the strip will I be polished so that an exceptionally smooth surface will be obtained. By provlding the rubber blocks and wedging members the desired pressure of the burnishers against the face of" the strip will be obtained, and as the rollers 5 are arranged cgposite the barnishers, the strip is prevented from yielding 'under the pressure of the burnishers.

i The strip then passes between a pair of revolving brushes 12 rotated by belt 13 driven by pulleys carried by shaft 14, which in turn are driven through the me diiim of gearing and belting constructed'as 80 arranged a support 8 in which are mounted shown in my companion applications, these brushes being carried by arms 15 which are adj ustably' mounted so that they can be held 'in contact with the opposite faces of the tically as shown in my companion application, Serial No. 314,464, wit the exception that the supporting means is slightly changed so that these receptacles can be arranged in transverse alignment with one another. The receptacle 16 is adapted'to contain a fluid wax which is applied to the highly polished surface of the stri as it passes over the discharge opening t ereof,

and the receptacle 17 is adapted to-contain an oil which coats the opposite surface of the strip so as topreserve the wood and prevent the same from warping; r

In use the receptacle 16 is provided with an agitator 18 driven in the same manner as shown in my companion application, Serial No. 314,464, so as to keep the liquid wax agitated, and as the receptacles are provided with removable bottoms having heat chamthe discharge opening thereof.

' carriage 20 provi bers, the fluid within" the receptacle will be maintained in a liquid state so that it can be readily applied to the strip Arranged on the machine at the delivery end a suitable lar polisher 23, comprising a disk 24 havin face of the strip 'soas to pc h the'waxed a circular member 25 secured thereto an provided with acentral circular projection 26 aroundwhich is wound a stri of clotl. of webbing 27 which enga es t e waxedsurface in order to obtain a higli'polished surfaceon the strip before it leaves the machine.

The construction of carriage is clearly shown and described in my companion applica t-ion and is operated by a hand wheel 28 so that the edge of the strip of fabric can be forced into contact with the face of the strip of flooring with the desired pressure so that v as the clrcular polisher is rotated the waxed surface will be polished.

. From the foregoing descriptionit will be se'en that I have rovided a machine for coating and-finishing a strip of flooring,

I which has been previously varnished, in such a manner that the strip is highly polished before it leaves the machine and at the same tune is given a coatingof oil, so a'sto preas passes (gnideway 19 is a movable ed with a support 21 on s which is mounted a shaft drivenby a belt '22, said shaft being provided with a circuserve the strip. It is of course understood that while I have described a machine for materials can be used, as a preservative compound can. be used. in place of the oil.

The operationis as-follows: Astrip of coating the strip with wax and oil, other flooring is forced into the guideway until it is engaged by the feed roller which causes the strip tomove continuously through the machine, and'asit passes the series of burnishers the face of the stri which has been previously varnished in t e machine con I structed as described in my companion ap-' lications, the varnished surface is polished. e strip then passes between the revolving brushes which remove all of the dust and foreign matter from the strip so that the strip willbe thoroughly 'cleanedas it passes between the discharge, openings of the wax and oil containing receptacles. The varnished face is given a coating of wax,and'

the op site face of the strip is given 'a coating 0 oil, and as the strip is moving con-- tinuously it is brought into contact with the revolving polisher so that the wax which' has been applied by the receptacle is-polished so that a complete strip of flodrm is produced which can be laid without furt 'er dressing of any kind. 'In this-machire, aswell machines shown in the companion applications, the feed rollers are so disposed that afterthe strip leaves the feed roller the movement is stopped so as to prevent the strip from being movedout of position in respect to the receptacle for applying a coat minfrom the receptacles.

the operation one strip is fed into the machine after another so that when one strip leaves the'-feed rollers another strip, is in contact with the feed rollers, and in engagement with the previously fed strip which causes the strips .to move continuously.

In .the drawings I have shown the receptacle for applying the wax and oilto the opposite faces of the strip in its passage t ough the machine arranged in transverse alignment, but I have found in practice that this is not essential, and in fact better a in' all 0' theing, which prevents the coating from escapresults when operating on certain kinds of lumber can be obtained by placing the oil receptacle at the end of the machine, so that all danger of the oil and wax becoming mixed in the passage of-the strip between the-receptacles is eliminated, and'I desire to reserve the right to place the oilreceptacle at the end of-the machine or at any ppsition desired.

I have described an apparatus for finishing flooring, but Idoaiot wish to limit myse f to the finishing of any particular kind of strip of lumber, as strips of molding and wainscotingcan be readily finished on an apparatus constructed in accordance with my invention, as I have described in the specification a guide-way having guide edges conforming in shape to the edge of the strip of lumber to be finished.

As this application is a companion application of applications Serial Numbers 314,464, 314,465 and 314,466, filed even date herewith, I wish it to be understood that the parts could be duplicated, or in other words, I am aware that it might bean advantage to first apply a coating of wax and then a c oating of oil on the faces of the strip.
